In which location would you most likely find volcanoes

What provides the force that causes magma to erupt to the surface

dissolved gasses trapped in the magma

sometimes rising magma is blocked by horizontal layers of rock. the magma forces the layers of rock to bend upwards into a landform called a

dome mountain

A pyroclastic flow typically occurs during a quiet eruption

false

a dike forms when magma forces itself between rock layers and hardens

false

a dormant volcano is erupting or may erupt near the future

false

volcanoes that form along a mid-ocean ridge occur at a diverging plate boundary

false

a string of islands known as what can form the collision of 2 oceanic plates

island arc

if geologists detect many small earthquakes in the area near a volcano, what can they infer about the volcano

it is probably about to erupt

molten material that leaves a volcanoes vent is called

lava

the main hazard from a quiet volcanic eruption is

lava flows

when many layers of thin, runny lava build up a high, level area, the result is a

lava plateau

before lava reaches the surface, the molten material is called

magma

the main factor that accounts for the difference between quiet and explosive eruptions

the silica content in the magma

ash, cinders, and bombs build up in a steep pile to form cinder cone volcanoes

true

which volcano hazard is made up of fine rocky particles as small as a speck of dust

volcanic ash

hardened magma in a volcanoes pipe that remains when softer rock around it has worn away is called a

volcanic neck

when magma hardens in a volcanoes pipe, the result will eventually be a landform called a

volcanic neck

In which location would you most likely find volcanoes

along mid-ridges and where a plate is subducted

the smallest lava fragments produced by an explosive eruption are called volcanic

ash

a mass of rock formed when a large body of magma cools inside the crust is called a

batholith

a mass of rock that forms when a large body of magma cools inside the crust is called a

batholith

the huge hole left by the collapse of a volcanic mountain is called a

caldera

when ash, cinders, and bombs build up in a steep pile near the volcanoes vent, the result is a

cinder cone volcano

Tall, cone-shaped mountains in which layers of lava alternate with layers of ash are called

composite volcanoes

mountains that are formed by volcanoes along a coastline occur at what plate boundary

convergent

where can volcanoes be found

convergent, divergent boundaries and hot spots

the bowl shaped area around a volcanoes central vent is called a

crater

a major volcanic belt known as the what circles the pacific ocean

ring of fire

describe how the state of Hawaii was formed

over a hotspot, magma rises, volcano erupts, plate moves

what kind of eruption is likely to occur in a volcano having magma that is low in silica

quiet
